STONE MOUNTAIN

Crystal Trio at Stone Mountain-Sue Kellogg Library

This Russian group uses glass for something other than tipping back vodka. Its music comes courtesy of glass instruments. Igor Sklyarov, Vladimir Perminov and Vladimir Popras are a harmonic glass ensemble, and they make their melodies using the glass harp, verrophone and glass pan flute. The musicians specialize in popular classical compositions from Bach to Mozart. If you miss the Stone Mountain show, the group plays another free show at 2 p.m. Sept. 22 at Lutheran Church of the Redeemer in Midtown.

1 p.m. Sept. 21. Free. Stone Mountain-Sue Kellogg Library, 952 Leon St., Stone Mountain. 770-413-2020, http://www.dekalblibrary.org/branches/stone-mountain.html.

LAWRENCEVILLE

“Walter Cronkite is Dead” at Aurora Theatre

Brian Clowdus directs this edgy comedy. When a thunderstorm shuts down the entire East Coast, a couple of strangers, two women from different backgrounds, decide to kill time over a bottle of wine. Their chat inevitably turns to politics, and the audience gets in on the act. As guests enter the theatre, they’re asked to randomly grab a button out of a bag. The button will be either red or blue, and each will represent a particular political party. The play stars Suzi Award-winning actress Lala Cochran, and Lane Carlock.

8 p.m. Thursdays-Saturdays; 2:30 p.m. Sundays. Through Oct. 6. $15. Aurora Theatre. Free parking at 153 Crogan St., Lawrenceville. 678-226-6222, www.auroratheatre.com.

NORCROSS

Cumberland Collective at Thrasher Park

This sprawling group of 15 singer-songwriters cull their talents and play like a jukebox of the mash-up variety. You might hear songs made famous by The Band, Bonnie Raitt, Marvin Gaye and James Taylor. They’ll take you up and down the pop charts, and on a detour for a drive through country music. One moment they’re injecting their tunes with contemporary soul, and the next they’re stopping at the crossroads for some old-school blues. Guests are welcome to kick back on blankets and lawn chairs. Coolers and picnic baskets are allowed, but glass isn’t. No time to pack some grub? Several downtown Norcross eateries are within walking distance, and they offer meals to go.

7:30 p.m. Sept. 21. Free. Thrasher Park, 93 Park Drive, Norcross. 678-421-2000, www.aplacetoimagine.com.
